Describe your suggestion
I need an example or guide on how to use this package on Windows. I tried using it like just_audio, but it didn't work. There was no error or exception of any kind thrown, so it would be helpful to have an example to follow and improve the Windows section in the just_audio package.

You just need to add just_audio_windows as a dependency for it to work. There aren't any significant changes.

[moha-b]

Yes, I agree with you, but the package has an issue. It didn't work the first time you tried to play. On the second click, it works.

in the beginning, I thought it was an issue I searched on it and I thought it was #30 the main project uses examples like issue #39

// This is OK
final _playList = ConcatenatingAudioSource(
children: [
AudioSource.uri(Uri.parse("http://localhost:5000/song1")),
AudioSource.uri(Uri.parse("http://localhost:5000/song2")),
AudioSource.uri(Uri.parse("http://localhost:5000/song3")),
AudioSource.uri(Uri.parse("http://localhost:5000/song4")),
]);

// This has NOT OK : progressbar lost position and got frozen when hit next song.
final _playList = ConcatenatingAudioSource(
children: [
AudioSource.uri(Uri.parse("asset:///assets/songs/song1.mp3")),
AudioSource.uri(Uri.parse("asset:///assets/songs/song2.mp3")),
AudioSource.uri(Uri.parse("asset:///assets/songs/song3.mp3")),
AudioSource.uri(Uri.parse("asset:///assets/songs/song4.mp3")),
]);

I attempted something similar, but it didn't work. Nothing plays and no errors appear. I searched extensively for an example of how to use it on Windows. Maybe I did something wrong, but as you said, it's the same implementation. So, I created a new project with only a button in the center and used this code.

 body: Center(
          child: ElevatedButton(
              onPressed: () async {
                final player = AudioPlayer();
                await player.setFilePath(
                    "C:\\$dir\\$dir\\$dir\\Documents\\muhammad_siddeeq_al-minshaawee\\100.mp3");

                player.play();
              },
              child: Icon(Icons.play_arrow)),
        ),

this was printed

After clicking again, it prints the same response and an additional line.

[just_audio_windows] Called play

The whole point is, if there is an issue that takes a lot of time to resolve, you can add a warning to the Windows readme to let us know about it instead of wasting a lot of time searching why it's not working.

[moha-b]

If you still see this and it doesn't matter, please close the issue.

Thanks for listening 🙏

[bdlukaa]

Can you run the app with Visual Studio and get the stacktrace from there? Thanks.

[moha-b]

hmm it works like that and this is Stacktrace

maybe the issue appear only with the audio source I will test it and update u

[bdlukaa]

@moha-b apparently play is being called before load, so it makes sense no audio is being played.

I did some checking and await player.setFilePath(...) does not await for the entire audio initialization, only for the call to the platform method. It may make sense to call .play after some defined time.
